New description:

 In''Whispers of a Machine'' (`ags:whispersofamachine`), activating the
 Muscle Boost augment has an indicator indicating that it is only active
 for a few seconds. When you interact with something while it is active, it
 continues to wind down smooththly in the original interpreter, but it
 stutters in ScummVM.

 == Reproduction Steps

 1. At any point in the game (except the part where she loses her
 augments), activate Vera's Muscle Boost augment
 2. Before the indicator reaches the bottom, click on something on the
 screen that requires her to walk a bit

 == Original behavior

 The indicator continues to smoothly go down, then if necessary smoothly
 goes back up. This includes during dialogue. See
 [https://bugs.scummvm.org/attachment/ticket/16608/Original.gif
 Original.gif].

 == ScummVM behavior

 The indicator stops, sometimes pausing until she reaches the object,
 sometimes resuming in a stuttering manner. During dialogue it pauses
 completely. See
 [https://bugs.scummvm.org/attachment/ticket/16608/ScummVM.gif
 ScummVM.gif].

 == Tested on

 * [https://store.steampowered.com/app/631570 Steam version of the game],
 macOS
 * ScummVM 2026.1.0, macOS
